OIL-CUP.

SPECIFICATION forming part of Letters Patent No. 676,561, dated June 18,1901.

Application filed March 28, 1901.

To all whom, it may concern:

Be it known that I, JOHN M. KING, a citizen of the United States,residing at Reading, in the county of Berks and State of Pennsylvania,have invented certain new and useful Improvements in Oil-Cups; and Ido'hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in oil-cups.

The object of the invention is toprovide a cup that will permit aconstant flow of fluid through a passage kept free at all times byreason of the construction and one that will permit with ease theopening and closing of the cup without endangering its hold on the partto which it has been secured.

My present construction embodies a solid or one piece body with meansfor readily opening the same for filling or to secure access to thevalve-stem.

The construction is fully set forth in the accompanyingdrawings andclearly described in the following specification.

Figure 1 is a vertical sectional view of my improved oil-cup. Fig. 2 isa plan view thereof. Fig.3 shows a screw-cap applied to my improved cup.Fig. 4 is a plan view of Fig. 3. Fig. 5 is a detail of the spring-cover.

The cup Ais preferably formed in one piece and has a cone-shaped centralinlet a at its top, extending some distance into the cup. The lower endis formed with the usual screw a and with a central opening atherethrough, while a valve-seat a is formed at the top of said openingin the base of the cup.

A plug B, having tapered body adapted to fit the opening a, forms aclosure for the cup. This plug is formed with a head b and has a hollowspace b extending nearlyits full length. Through its top a set-screw 0passes, provided with a jam-nut d, and its end 0 depends some distanceintothe space I). r

A spring-cover E fits loosely over the head I) of the plug and whileapproximately circular is formed with two diametrically oppositesemicircular depressions e, adapted to register with two screws f, setinto the cup on either side of the opening 66. This cover is slightlytapered on its upper face for a short Serial No. 53,196. (No model.)

distance on either side of the depressions e to permit them to moreeasily enter under the heads of the screws f, and it also has athumb-piece or extension (2 to facilitate its movement.

The valve-spindle F extends through the full length of the cup into thehollow space 1) of the plug and has a valve 2) formed near its lowerend, adapted to seat against the point a of the cup-base, and its lowerextension f while somewhat smaller in diameter than the body, passesentirely through the screw a and has a tapered end f depending below it.In other words, the spindle passes entirely through the cup and extendsabove its top and below its lower surfaces. The

valve-spindle is regulated in its movementby means of the set-screw C,which when properly regulated is secured in that position by means ofthe nut (I, thus insuring it against becoming loose and changing theregular flow of oil.

The plug B fits snugly in the opening a, and the spring-cover, whichfits loosely over the headb, is so placed that the depressions e thereinregister with the screws fand permit it to drop to the surface of thecup, and by turning it by means of the thumb-piece c it will tightenthereunder by reason of the tapered surfaces 6 wedging under saidscrewheads, thus securely holding the plug in position in the cup.

The valve-spindle F, having its lower end f extending entirely throughthe screw at the bottom of thecup, will prevent clogging of the oil in"the passage thereof by reason of the constant movement therein of thespindle, and should it become clogged by reason of having remainedstationary for any length of time the spring-cover can be easily turned,the plug lifted out, and the end of the spindle F which extends abovethe upper surface of the cup can be taken hold of and moved up and downto open the passage. The tapered lower end f of the spindle F will causethe oil to drop from that point and will prevent the tendency of the oilfrom working its way out around the lower surface of the screw a.

In Figs. 3 and 4 I vention can be applied to a screw-cap-as, forinstance, where the body of the cap is have shown that my informedintegral with the part to be lubri cated. In such case it will benecessary to have a separate cover, and I have shown that the cover mayembody the features of my invention.

Having thus fully described my invention, what I claim is 1. In anoil-cup, the one-piece body with central opening in its top, a recessedplug adapted to fit said opening, screws set in said cup on either sideof said opening, a springcover adapted to fit loosely over said plug andhaving notches adapted to register with said screws and having a centralopening, a setscrew in the top of said plug with a jam-nut thereon, anda removable valve-spindle seated in the base of said cup and havingitsupper end extending above the upper surface of the cup and into therecessed plug, while its lower end passes through the base of said cupand depends below its surface, substantially as set forth.

2.- The combination of a one-piece oil-cup having screw-heads insertedin the top thereof and having a central tapered opening,with

a lower tapered end and passing entirely through the cup and into thehollow plug, all substantially as set forth.

3. A one-piece oil-cup having screw-heads f inserted in the top thereofand having a central tapered opening in its top, a recessed plugcarrying a valve-spindle regulator adapted to fit said opening, ataper-ed Valve-spindle F and a spring-cover, having tapered surfaces,adapted to engage the screw heads f and to securely hold said plug inposition all substantially as and for the purpose set forth. Intestimony whereof I affix my signature in presence of two witnesses.
